Azure DevOps Rest API missing data for service connection checks config (required template, etc)

[edmondandy]

couldn't get it working by using ADO rest API to get information for service connection's checks configs, e.g. required templates, branch controls, etc. 

the setting is under project settings-> service connections -> approvals and checks

basically I tried /_apis/policy/configurations, 

_apis/pipelines/checks/configurations,

_apis/serviceendpoint/endpoints,

couldn't find the required information, can you please advise how i can retrieve these information and update it via rest api for bulk operations? thanks

I made a few guesses with the parameters, and then I was able to retrieve the information like this:

/_apis/pipelines/checks/configurations?&$expand=settings&resourceType=endpoint&resourceId={id of service connection}

Where id of service connection is from /_apis/serviceendpoint/endpoints
